CLOTH-SPRAYING APPARATUS.

Application filed December 4, 1922. Serial No. 604,972.

To all whom it may concern:

Be it known that I, IsAAo CRYSTAL, a citizen of the United States, residing at New York city, borough of Manhattan, in

6 the county of New York and State of New York, have invented certain new and useful Improvements in Cloth-Spraying Apparatus, of which the following is a specification. I

1 This invention relates to the treatment of cloth for the purpose of permanently mothproofing the same andhas particular reference to mechanism or means for spraying the cloth coincidentally with the mothproofing action. In the modern practice of the inspection and A treatment of cloth in the leading large establishments preparatory to the conversation of cloth into clothing there is a demand for so treating the cloth as to render the same permanently mothproof,

a process now 'known as larvexing, and it is to this art or process to which my present apparatus, shown and described herein, particularly relates. Among the objects of the invention therefore, is to providea machine or means by the practice or operation of which the mothproofing or larvexing is performedrapidly in a continuous operation. 7

Another. object of the invention is to provide a'practical, reliable, and rapid apparatus for the treatment of cloth including the delivery to or into the cloth while it is in rapid motion through the machine, of a hot vapor and spray which serves the purpose of spraying the cloth for conveying the larvex, or permanent moth proof substance, to the cloth whereby the cloth properly and quickly is rendered mothproof.

A still further object ofthe invention is to provide an improved and rapid spraying apparatus calculated not only to serve any usual spraying purpose, but also to increase the beauty of the texture while rendering cloth permanently mothproof;

With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invenof construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is 5 had to the accompanying drawings, in 5 terial, or construction, and extending upsubstantially the full length of the machine.

tion is not restricted to the exact details which like reference characters designate the same which Figure 1' is a front elevation of a preferred embodiment of this apparatus. Fig. 2 is an end elevation of the same,*i'ndicating especially the direction of movementof the cloth while the machine is operating. Fig. 3 is a vertical transverse sectional view of the larvex tank and the apparatus associateddirectly therewith. 1

Referring now more specifically to thedrawings I show an apparatus comprising a base frame 10 of any suitable design, ma-

parts in the several views, and in.

ward therefrom is a supplementary frame 11 The main base frame 10 supports the motor M and the'principal other operating parts of the apparatus, it being understood however that in some instances the motor might be supported elsewhere or otherwise.

' Shown disposed close back of the motor is a tank 12 having a preferably cylindrical bottom and an open top and extending This tank containsthe mothproofing fluid or larvex and from which it is delivered by suitable means directly rearward in a finely comminuted condition to or into the cloth C as it is transferred upward from the base portion of the machine over any suitably arranged guide rolls 13 to the roller 14 upon which it is wound as by the operation of a traction roller. 15, the operation of whichis effected by 'means of a power belt or chain 16. As is well understood the roller 14 is lifted and guided along suitable guide arms 17 automatically as the diameter thereof increases with the cloth rolled thereon.

" The mothproofing fluid in the tank 12, may be supplied thereto from any suitable source, as for example, from an overhead reservoir 18 supported upon the auxiliary frame 11, such reservoir charged ordinarily once every day and from which the material may be delivered at any time during the day through a pipe 19- into the tank 12. The larvex or mothproofing material includes ingredients that have a tendency to precipitate or settle to the bottom of the fluid. Hence means must be provided to keep the fluid suitably agitated for the purpose of maintaining theprecipitate suitably suspended so that the proper consistenc of the fluid or material may be maintaine I provide therefore agitating means within shaft 20 is a large gear or pulley 22 over which a'chain or belt 23 operates from the motor pinion 24; and whereby while the motor is in operation the agitator will be rotated Within the tank at a relatively low rate, the paddles 21 serving at such time to I keep the fluid suitably stirred and the in- 7 equivalent. At any time preferably before gredients all in proper mixed condition. VVi'thin the reservoir 18 I provide also agitating means including a shaft 25 and any suitably arranged paddles 26 or their delivery of a new supply of the fluid from the reservoir I rotate the shaft 25 by any suitable means suchas a hand wheel or crank 27 outside of one end'thereof so that the material will be delivered through the pipe 19 inproper consistency. 28 indicates a vent at the top of the reservoir serving to insure proper movement of air. out of or int-o the reservoir when the same is being filled or emptied. l

' Located along the top of the tank 12 and substantially-parallel to the shaft 20 is a steam pipe 29 one end of which is closed while the other is connected to any suitable source of steam supply, the supply to the pipe being controlled by means of a valve 30 within easy reach of the operator of the machine. Secured by any suitable clamping means or otherwise upon said steam pipe 29 are a series otjets or nozzles 31, the same being preferably equaliy spaced along the pipe and tank and directed rearward toward the cloth-as it is moving upward in a substantially vertical plane just back of the tank. Associated with each nozzle 31 is a bracket 32 by means of which a feed pipe 33 of simple tubular form, open at both ends, is maintained in rigid position suitably adjusted with respect to the end of the nozzle, the upper end of the feed pipe being disposed substantially at the center or axis of the nozzle and close to the rear thereof while the lower end of the feed pipe extends downward into the tank at one side of the shaft 20 toward the bottom of the tank. The 'feed pipe is gripped as by a set screw 34 to a bracket arm 35 and whereby it may be delicately adjusted vertically, while the arm 35 is adjustable along its own axis in the bracket 32 by means of lock nuts 36. The bracket 32 is locked in place by a nut 37 against the body of a valve 38 which regulates the volume and force of the steam delivered therethrough from the pipe 29. A blast of steam through each nozzle 31 causes the fluid to be drawn upward from the tank 12 through the adjacent feed pipe 33, by an injector action, where it is mixed with the hot steam and so is delivered in a properly mixed moisthot vapor to the cloth 0 and whereby the cloth is simultaneously sprayed and larvexed.

Any water of condensation .t'ormed in the pipe 29 may be drained oil through a pipe 39 adjacent to the closed end of the pipe 29. A pipe 40 is shown provided for the drainage of the tank 12 and which will of course be normally closed while the machine is in use. The reservoir is filled through an inlet 42 at the top, and at one end is shown a gage glass 43 to indicate the level of the fluid within it. i

I claim:

In a cloth spraying apparatus, the combination of a horizontally disposed tank for containing a liquid mothproofing substance, means to operate a strip of cloth at a predetermined rate of speed along said tank, agitating means within the tank for maintaining the liquid in proper consistency, means to drive the agitator means and the cloth operating means simultaneously, and means operative above the tank for drawing regulatable quantities of the liquid from the tank and driving it into the cloth while the latter is in motion, the last mentioned means including a series of feed pipes having open ends, the lower end of each reaching toward the bottom of the tank and the upper end thereof extendin above the tank, and steam jets acting over t 1e respective upper ends of said feed pipes whereby the liquid drawn from the tank is thoroughly mixed with the steam, forming a hot vapor suitably charged with the mothproofing material for impregnation in the cloth.

In testimony whereof I afli'x my signature.

ISAAC CRYSTAL.
